JOI-IN KANE, OF PASSAIO, NEV JERSEY, ASSIG-NOR TO THE MANHATTAN RUBIABER MFG. OO., A CORPORATION OF NEIV JERSEY.

ORE-CONCENTRATOR BELT.

SPECIFICATION forming part of Letters Patent No. 776,744, dated December 6, 1904.

Application filed April 2,1904;I Serial No. 201,272. (No model.)

To @ZZ 'Ll/71,0111, it may cm1/cern.'

Be it known that I, JOHN KANE, a citizen oi the United States, and a resident of Passaic, county ot' Passaic, and State ot' New Jersey,

5 have invented a new and useful Improvement in Oie-Ooncentrator Belts, o'lI which the lfollowing is a specification.

Ore-concentrator belts are usually made of rubber or canvas, or both, in endless ilorm and I in use are supported by rollers around which they move. Such belts are usually provided with side Vl'langes extending approximately at right angles to the surface of the belt, the purpose ot' which is to confine the material being I treated on the belt. At the points where the belt passes around the supporting-rol lers these flanges are subjected to a stretching strain, which is very destructive to them, and to provide against which various devices or forms 2O of 'liange have been proposed.

I have discovered that by corrugating the upper edge oil the iianges they are enabled to stand the strain above referred to without destruction.

In the accompanying drawings, Figure l is a perspective view of a section cut from an endless belt containing my invention. Fig. 2 is a side view of the same.

The body or floor of the belt consists oi the canvas l, coated by the rubber 2 3. 4 and 5 are the side flanges composed of rubber coinpounds which when vulcanized are substantially integral with the coatings 2 and 3, but

oi: so'lter composition, so that the `l'langi-is are more pliable and elastic than is the body or l'loor of the belt. The upper edge of each flange is corrugated, as at 6, so that when the flange passes around a supporting-roller the consequent lengthening or stretching of the upper edge of the iiange instead of splitting or 40 breaking the edge has atendency to straighten the corrugations, and thereby prevent the destruction o'f the flange.

It will be observed that the corrugations of the edge ol the llange are substantially parallel with the surface oiE the belt, being therefore distinct both in construction and mode of operation from any belt in which the lianges are corrugated at right angles to the surface of the belt.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A belt for ore coneentrators having continuous side iianges of vulcanized rubber sur 55 mounted by integral transverse upwardly-extending edge projections.

In testimony whereof l have hereunto signed my name in the presence oi' two subscribing witnesses.
